UDC 3300 Controller has sealed faceplate suitable for housedown

New Power and Flexibility

The UDC 3300 Universal Digital Controller packs new powerful features in the popular 1/4 DIN size while retaining all the simplicity, flexibility, accuracy and industry-leading MMI of the UDC 3000. For the many thousands of satisfied UDC 3000 users, the UDC 3300 is totally downward compatible to existing UDC 3000 applications and installations. It even uses the same case.
Unmatched new application power includes: two universal analog inputs, two loops of control, two Math equations, two characterizers and a totalizer. When these are combined with the new Accutune Il™ tuning with fuzzy logic overshoot suppression, the result is price/performance leadership. Application flexibility is assured by the universal analog inputs, universal AC power supply, two digital inputs, RS422/485 ASCII or Modbus RTU communication protocols, simple configuration plus total field upgrade capability for any optional feature.

Features/Options

Universal Inputs — Up to two isolated universal inputs, accepts thermocouple, RTD, mA, mV and volt input types. All input types are configurable without switches and there is no need to calibrate. The two inputs can be optionally combined to provide direct calculation of Carbon Potential, % Oxygen, or Percent Relative Humidity. As an optional feature, the second universal input can be converted into two separate 1-5 volt/4-2OmA high level inputs to provide a total of three analog inputs.

• Math Functions -Optional
  — Feedforward summer (standard)
  — Summer/subtracter
  — Weighted average
  — Multiplier/divider
  — Feedforward multiplier
  — Hi/lo select
  — Two characterizers
  — Totalization

• Two Loops of Control (Optional)
  Two independent loops or internally cascaded loops in one device.

• Accutune II
  — This feature provides a plug-and-play tuning algorithm that will accurately identify and tune any process, including deadtime and integrating processes. Accutune II speeds up and simplifies start-up, and allows retuning at any setpoint.

• Fuzzy Logic
  — This new feature suppresses process variable overshoot resulting from setpoint changes or externally induced process disturbances. It operates independently from Accutune II tuning, and it does not change the PID constants, but temporarily modifies the internal controller response to suppress overshoot. This allows more aggressive tuning to co-exist with smooth process variable response. Fuzzy logic can be enabled or disabled depending on the application or the control criteria.

• Universal Output
  — UDC 3300 provides “out-of- the-box” operations, with no need to open the case. There are no jumpers to connect, no switches to set, and no required hardware configuration.

• Heat/Cool Capability
  — Provides split-range control with independent PID tuning constants for heating and cooling, plus mixed output forms.

• Two Digital Inputs (optional)
  — User configurable with 24 selections.

• One or Two Current Outputs
  — 4-2OmA
  — Isolated

• Serial Communications (Optional)
  — RS422/485 - ASCII
  — Modbus RTU
